MAZS0620ML Equivalent & Substitute Parts

Part Overview

The MAZS0620ML is a 6.2 V Zener diode rated at 150 mW manufactured by Panasonic Electronic Components in the SSMini2-F1 surface mount package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. Substitute parts must maintain the 6.2 V nominal Zener voltage while accommodating variations in power dissipation, impedance, and package configurations within the SOD-523 and related surface mount families.

Substitute Part Grouping Explanation

Substitution of the MAZS0620ML is determined by the following critical parameters:

Primary Matching Criteria:

Voltage - Zener (Nom): 6.2 V (exact match required)
Mounting Type: Surface Mount
Package / Case: SC-79 or SOD-523 compatible

Secondary Compatibility Factors:

Power - Max: Substitute parts rated at 150 mW or higher are acceptable
Impedance (Max): Substitute parts with 10 Ohms or higher impedance are acceptable
Tolerance: Substitute parts with ±2% to ±5% tolerance are acceptable
Moisture Sensitivity Level: MSL 1 (Unlimited) required

All substitute parts listed maintain the 6.2 V Zener voltage specification and surface mount configuration. Variations in power rating, impedance, and tolerance reflect different manufacturer designs while preserving functional equivalence for the primary application requirement.

Engineering Selection Recommendations

Direct Equivalents (SOD-523 Package):

The EDZVFHT2R6.2B from Rohm Semiconductor provides the closest functional match to the MAZS0620ML, maintaining identical 150 mW power rating and SOD-523 package configuration. This part is active in production status with ROHS3 compliance and AEC-Q101 automotive qualification.

The BZX585-B6V2,115 and BZX585-B6V2,135 from Nexperia USA Inc. offer higher power dissipation (300 mW) in the same SOD-523 package with improved impedance characteristics (10 Ohms). Both variants are active, ROHS3 compliant, and carry AEC-Q100 automotive qualification.

The BZT585B6V2T-7 from Diodes Incorporated provides the highest power rating (350 mW) among SOD-523 options with active product status and ROHS3 compliance.

Alternative Package Option (SOD-323F):

The BZX84J-C6V2,115 from Nexperia USA Inc. operates in the larger SOD-323F package with 550 mW power rating. This part is active, ROHS3 compliant, and carries AEC-Q101 automotive qualification. Package substitution requires PCB layout modification.

Selection Basis:

All substitute parts maintain the 6.2 V Zener voltage specification and surface mount configuration. Selection should prioritize active production status parts with current compliance certifications (ROHS3). For applications requiring automotive qualification, BZX585-B6V2 variants and BZX84J-C6V2,115 are qualified to AEC-Q100 or AEC-Q101 standards. For applications with strict power budget constraints matching the original 150 mW specification, EDZVFHT2R6.2B is the preferred selection.

Frequently Asked Questions (FAQ)

Q: Can the MAZS0620ML be directly replaced with any of the listed substitute parts?

A: Direct replacement depends on package compatibility and circuit requirements. The EDZVFHT2R6.2B, BZX585-B6V2,115, BZX585-B6V2,135, and BZT585B6V2T-7 are pin-compatible in SOD-523 packages. The BZX84J-C6V2,115 uses SOD-323F package and requires PCB layout modification. All maintain the 6.2 V Zener voltage specification.

Q: What is the significance of the impedance difference between the MAZS0620ML (30 Ohms) and substitute parts (10 Ohms)?

A: Lower impedance in substitute parts indicates improved dynamic response characteristics. Impedance values of 10 Ohms are acceptable for applications originally designed for 30 Ohms, as lower impedance provides equal or superior performance in voltage regulation applications.

Q: Are the substitute parts with higher power ratings (300 mW, 350 mW, 550 mW) suitable for circuits designed for 150 mW?

A: Yes. Higher power-rated Zener diodes are suitable for 150 mW applications. The power rating indicates maximum dissipation capability; actual power dissipation is determined by circuit design. Higher-rated parts provide design margin and thermal headroom.

Q: What is the impact of tolerance differences (±3% original vs. ±2% or ±5% substitutes)?

A: Tolerance variations affect Zener voltage accuracy. The ±2% tolerance of most substitute parts provides tighter voltage regulation than the original ±3%. The ±5% tolerance of BZX84J-C6V2,115 is wider but remains within acceptable ranges for most applications. Circuit design should account for the specified tolerance of the selected part.

Q: Which substitute part is recommended for automotive applications?

A: BZX585-B6V2,115 and BZX585-B6V2,135 carry AEC-Q100 qualification. BZX84J-C6V2,115 and EDZVFHT2R6.2B carry AEC-Q101 qualification. Selection depends on specific automotive qualification requirements.

Q: Is the package change from SSMini2-F1 to SOD-523 significant?

A: SSMini2-F1 is a supplier-specific designation for the SOD-523 package. The SOD-523 package designation is the industry standard. Substitute parts specified as SOD-523 are mechanically and electrically compatible with the original SSMini2-F1 package.

Q: What is the relevance of reverse leakage current differences?

A: Reverse leakage current affects standby power consumption and temperature stability. The original part specifies 200 nA at 4 V. Substitute parts with 1 µA to 3 µA leakage are acceptable for most applications. Lower leakage (EDZVFHT2R6.2B at 1 µA) provides improved performance in low-power standby conditions.
